2004 Chevy Silverado valve sticking?

I have a 2004 Chevy Silverado. 2 months ago I noticed I was loosing coolant. But I am not finding it on the ground. Now a valve or something is sticking (ticking). Once the truck warms up or I rev it to 3000 RPMs then it stops ticking. HELP!

what causes yellow gunk in the oil cap on my 2004 chevy trailblazer


Could be a leaking head gasket or intake gasket.
The gunk is water or coolant. Water if the engine never warms up, coolant if there is a leak.

Chevy 2000 Silverado 1500, the engine stalls and won't start until it has cooled off.


You'll have to figure out if it is a fuel or ignition problem.
Is the check engine light on ?

I have a 2000 Chevy Silverado pickup, and the heater will not blow hot air. I replaced the thermostat, and nothing changed. The radiator was flushed and filled in the last two months as well. I have all cold air all the time.


once truck is warm check both heater core hoses to make sure they are both warm if not then check the cold water valve could be stuck shut not allowing coolant to travel in to heater core.

2001 chevy silverado 5.3 ltr I am adding 1 gallon of antifreeze between oil changes. I am not seeing any in the oil, and it not leaking. Where is it going?


This is one that you will need to do some careful looking to find. every hose connection needs to be looked at for damp residue as well as all gasket parting lines (thermostat housing, head to block parting lines, intake manifold ends etc.) You may also need to have a shop to a radiator pressure test as well as a cylinder leakdown test (which will pick up on most internal leaks) If seepage is very minor, coolant can burn off or boil out before reaching a noticeable level inside the engine or even at a gasket to the outside. A small crack between the valves in a cylinder head can be so small that it goes unnoticed when exiting along with exhaust. A small leak now may be difficult to find but locating it now is better than waiting for a larger failure. It may turn out to be something simple as a bad cap on the radiator or the shaft seal beginning to fail on your water pump...letting it go can eventually cost you an engine.
